    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

environment-setup-assistant scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/setup_docker.sh, scripts/setup_nodejs.sh, scripts/setup_python.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Environment Setup Assistant

Generate automated setup scripts and detailed instructions for development environments across multiple platforms.

Quick Start

Generate Setup Script

Specify your requirements and get an automated setup script:

# Example: Python development environment
bash scripts/setup_python.sh

# Example: Node.js development environment
bash scripts/setup_nodejs.sh

# Example: Docker environment
bash scripts/setup_docker.sh

Get Platform-Specific Instructions

For manual setup or understanding what the scripts do, see platform_instructions.md.

Common Setup Scenarios

Scenario 1: New Team Member Onboarding

Goal: Set up complete development environment for a new developer

Approach:

  1. Identify target platform (macOS, Linux, Windows)
  2. List required tools (Git, Python, Node.js, Docker, etc.)
  3. Generate comprehensive setup script
  4. Provide verification checklist

Example Request: "Set up a Python and Node.js development environment on macOS"

Generated Output:

#!/usr/bin/env bash
# Complete Development Environment Setup

# Install Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install Git
brew install git

# Install Python via pyenv
brew install pyenv
pyenv install 3.11.0
pyenv global 3.11.0

# Install Node.js via nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
nvm install --lts

# Install Docker Desktop
echo "Please download Docker Desktop from https://www.docker.com/products/docker-desktop"

# Install VS Code
brew install --cask visual-studio-code

# Verify installations
git --version
python --version
node --version

Scenario 2: Project-Specific Setup

Goal: Set up environment for a specific project with exact dependencies

Approach:

  1. Analyze project requirements (package.json, requirements.txt, etc.)
  2. Detect required runtime versions
  3. Generate setup script with project initialization
  4. Include virtual environment or project-specific configuration

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
